AMD Athlon processors received a huge boost in performance when the motherboard manufacturers transitioned from SDRRAM based systems to DDR. Regardless of the gains PC1600 DDR and PC2100 first brought to the table, the performance market craved more, and shortly thereafter PC2400 and PC2700 rated DDR began to pop up. Sooner or later, even the mighty PC2700 DDR333 would be surpassed by something better and faster. The next level in DDR memory was met by PC3000, or DDR366. Priced at about $90USD for a 256MB stick, it's some of the least expensive high performance DDR DIMM's available.
